Description

Technical Field

[0001] This utility model relates to the field of biomimetic robotic fish technology, specifically a modular biomimetic robotic fish. Background Technology

[0002] Intelligent bionic robotic fish is a type of robot that mimics the shape and movement of fish. Currently, the battery in a typical bionic robotic fish is placed in the middle of the fish's body. Placing the battery in the middle of the fish's body is relatively stable, allowing the robotic fish to maintain good balance when swimming in water. At the same time, because it is in a relatively central position, it has less impact on the overall center of gravity of the robotic fish, which helps the robotic fish maintain a stable posture and direction during movement.

[0003] However, the battery in the bionic robotic fish is located in the middle of the body. If the battery needs to be replaced, the waterproof shell of the robotic fish needs to be disassembled, which is relatively complicated. In other words, the battery replacement rate of the bionic robotic fish is slow. In view of this, this paper proposes a modular bionic robotic fish that is easy to replace the battery. Utility Model Content

[0004] The purpose of this invention is to solve the problem of slow battery replacement rate in existing bionic robotic fish, and to propose a modular bionic robotic fish.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular biomimetic robotic fish includes a shell module and a battery module. The battery module is detachably fitted and installed under the fish body of the shell module, and the shell module and the battery module are fixedly connected by a bolt structure, which is disposed in the battery module.

[0007] Preferably, a battery slot is provided below the fish body of the casing module, which is fitted with the battery module. The battery module includes a waterproof cover, two lithium batteries and a fixing block. The waterproof cover and the lower opening of the battery slot are fitted with each other. The lower end of the fixing block is vertically fixed above the waterproof cover. The two lithium batteries are respectively fixedly installed on the waterproof cover on both sides of the fixing block.

[0008] Preferably, the bolt structure includes a cylinder and a screw that are coaxially fixedly connected. The top end of the screw is threaded into a threaded hole in the top surface of the battery compartment, and the cylinder is rotatably installed in a circular hole in the fixing block.

[0009] Preferably, a plurality of second electrodes are disposed above the lithium battery, and a plurality of first electrodes corresponding to the second electrodes are disposed on the inner top surface of the battery slot.

[0010] Preferably, a second sealing strip is fitted to the inner edge of the waterproof cover, and a first sealing strip is fitted to the upper edge of the two lithium batteries. Furthermore, the battery slot is connected to an outer slot and an inner slot that correspond to the first and second sealing strips, respectively.

[0011] Preferably, a circular piece larger than the inner diameter of the circular hole is coaxially fixedly installed below the cylinder, an annular groove is coaxially provided on the outer periphery of the upper end of the cylinder, a rubber ring is extruded in the annular groove, the outer diameter of the rubber ring is larger than the inner diameter of the circular hole, and the circular piece and the lower end of the cylinder are coaxially provided with interconnected internal hexagonal prism holes.

[0012] Compared with the prior art, this utility model provides a modular biomimetic robotic fish with the following features:

[0013] Beneficial effects:

[0014] This modular bionic robotic fish allows for the detachable installation of the battery module directly under the fish's body within the casing module. This enables the removal and installation of two lithium batteries from the battery module, placing them in the middle of the modular bionic robotic fish. Compared to existing technologies for replacing batteries in bionic robotic fish, this method is more convenient, faster, and more efficient. If the battery module needs to be replaced, there is no need for extensive disassembly of the bionic robotic fish's outer shell. Simply turning the screw disengages it from the threaded hole in the battery slot within the casing module, thus separating the battery module from the casing module. Then, the new battery module is inserted into the battery slot within the casing module, and turning the screw again tightens it into the threaded hole within the battery slot, securing the new battery module. The operation is simple and convenient. When the screw is spirally drilled into the threaded hole, the upward-moving screw, through the disc and waterproof cover, presses and seals the sealing rings one and two into the outer slot and battery slot respectively, ensuring a sealed and waterproof connection of the two lithium batteries within the battery module to the casing module.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] See attached document Figure 1-3 A modular biomimetic robotic fish includes a shell module 1 and a battery module. The battery module is detachably fitted and installed under the fish body of the shell module 1, and the shell module 1 and the battery module are fixedly connected by a bolt structure. The bolt structure is set in the battery module. A battery slot 3 is provided under the fish body of the shell module 1 and is fitted with the battery module.

[0022] Furthermore, an outer slot 4 is connected to the lower opening of the battery compartment 3, and an inner slot 5 is connected to the inner top surface of the battery compartment 3. The top end of the screw 17 is threaded into the threaded hole 7 in the inner top surface of the battery compartment 3, and several electrodes 6 are fixedly arranged on the inner top surface of the battery compartment 3. The aforementioned electrodes 6 are the access points for the circuit input connection in this modular bionic robotic fish.

[0023] In this embodiment, the battery module includes a waterproof cover plate 8, two lithium batteries 9 and a fixing block 11. The waterproof cover plate 8 and the lower opening of the battery slot 3 are fitted together. The lower end of the fixing block 11 is vertically fixedly installed on the top of the waterproof cover plate 8. The two lithium batteries 9 are respectively fixedly installed on the waterproof cover plate 8 on both sides of the fixing block 11. The two lithium batteries 9 are symmetrically arranged on the waterproof cover plate 8 so that the battery module can be installed in the battery slot 3 in both directions.

[0024] Several electrodes 10 are fixedly arranged on the top of the lithium battery 9. The electrodes 10 on the two lithium batteries 9 correspond to the electrodes 6 on the inner top surface of the battery slot 3. A sealing ring 14 is attached to the inner edge of the waterproof cover plate 8. A sealing ring 13 is attached to the upper edge of the two lithium batteries 9. The sealing ring 13 and sealing ring 14 are respectively fitted and sealed to the outer slot 4 and the inner slot 5.

[0025] In this embodiment, the bolt structure includes a cylinder 16 and a screw 17 that are coaxially fixedly connected. The top end of the screw 17 is threaded into the threaded hole 7 in the top surface of the battery compartment 3, and the cylinder 16 is rotatably installed in the round hole 12 in the fixing block 11.

[0026] A circular piece 18, larger than the inner diameter of the circular hole 12, is coaxially fixedly installed below the cylinder 16. An annular groove 19 is coaxially provided on the outer periphery of the upper end of the cylinder 16. A rubber ring 15 is squeezed into the annular groove 19. The outer diameter of the rubber ring 15 is larger than the inner diameter of the circular hole 12. The circular piece 18 and the lower end of the cylinder 16 are coaxially provided with interconnected internal hexagonal prism holes 20. A knob 2 is detachably installed in the internal hexagonal prism hole 20 by a screw. After the knob 2 is installed, it is convenient to operate the cylinder 16 and the screw 17. If the knob 2 is not installed below the internal hexagonal prism hole 20, the camouflage performance of this modular bionic robotic fish is higher.

[0027] As can be seen from the above, when the two lithium batteries 9 in the battery module are fitted into the battery slot 3 in the housing module 1, and the electrodes 10 on the two lithium batteries 9 correspond to the electrodes 6 in the housing module 1, the top of the screw 17 in the bolt structure also corresponds to the threaded hole 7 in the battery slot 3. At this time, the entire screw 17 can be rotated by a hex wrench or by directly using the knob 2, and the screw can be spirally drilled into the threaded hole 7. The upward-moving screw 17 can use the disc 18 and the waterproof cover plate 8 to squeeze and seal the sealing ring 13 and sealing ring 14 in the outer slot 4 and the battery slot 3 respectively, thereby ensuring that the two lithium batteries 9 in the battery module are sealed and connected in the housing module 1.

[0028] This invention allows for the detachable installation of the battery module of a modular bionic robotic fish directly onto the underside of the fish's body in the housing module 1. This enables the removal and placement of the two lithium batteries 9 from the battery module in the middle of the modular bionic robotic fish. If the battery module needs to be replaced, extensive disassembly of the bionic robotic fish is unnecessary. Simply turning the knob 2 disengages the screw 17 from the threaded hole 7 in the battery slot 3 of the housing module 1, thus separating the battery module from the housing module 1. This method offers high replacement efficiency. The new battery module is then inserted into the housing module. After the new battery module is inserted into the battery slot 3 in section 1, the screw 17 can be tightened into the threaded hole 7 in the battery slot 3 in the housing module 1 by turning the knob 2. This achieves the purpose of fixing the new battery module. Compared with the replacement of batteries in the bionic robotic fish in the prior art, this is more convenient and faster. When the screw 17 is spirally drilled into the threaded hole 7, the upward-moving screw 17 can use the disc 18 and the waterproof cover plate 8 to squeeze and seal the sealing strip ring 13 and sealing strip ring 14 into the outer slot 4 and the battery slot 3 respectively, thereby ensuring that the two lithium batteries 9 in the battery module are sealed and connected in the housing module 1.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
